There has been significant interest in electrically controlled information writing using artificial multiferroic to develop scalable energy-efficient spintronics devices [1]}, [2]}, [3]}, [4]}, [5]}. Various methods such as current-induced spin-transfer torque (STT), external magnetic field (using electromagnet), etc., are employed to achieve the magnetization switching in such a system [6]}, [7]}, [8]}, [9]}. However, these are still facing challenges due to requirement of resource intensive magnetic field generation system and the energy loss in the form of Joule heating in current driven STT system. Therefore, developing magnetic memory with electric write and magnetic read is one of the highly desirable approaches for ultralow-power spintronics [10]}, [11]}, [12]}. Magnetoelectric-multiferroic systems consisting of more than one ferroic order are important material choices with the ability to control the magnetization using dual stimulus [13]}, [14]}, [15]}, [16]}, [17]}, [18]}, [19]}, [20]}. However, using single-phase multiferroic materials is challenging due to weak magneto-electric coupling at room temperature [21]}. Therefore, magneto-electric multiferroic heterostructure consisting of independent ferromagnet and ferroelectric have been explored as a promising candidate because of the significant magneto-electric coupling well above at the room temperature [22]}, [23]}.
Magnetization manipulation has been realized through different routes, including charge coupling, exchange coupling, strain coupling, etc. [24]}, [25]}, [26]}, [27]}. Among these, magnetization switching through strain-mediated magneto-electric coupling is demanding due to the long-range transfer of piezoelectric strain. Theoretically, it is proposed
that utilizing piezoelectric strain allows one to write information at ultralow energy of the order of aJ/bit [28]}.
In recent years, the nanoscale patterned ferromagnet coupled with the ferroelectric has been the subject of great interest to control the magnetization through piezoelectric strain [29]}, [30]}, [31]}, [32]}. Fundamentally nanomagnets offer scalable, stable and simple magnetic states, making them an ideal candidate for the studies of magnetization dynamics [33]}, [34]}. Several attempts for magnetization switching in the patterned nanomagnetic system have been made utilizing artificial multiferroic heterostructure [35]}, [36]}.
However, the challenge of achieving piezoelectric strain-controlled magnetization switching in multiferroic artificial spin ice systems (ASI) is still unexplored.
